Some people must have colonoscopy regularly

Some people must have colonoscopy regularly. Why do you get colorectal cancer after annual physical examination? These seven types of people must have colonoscopy regularly!

First, why do you still get colorectal cancer after doing physical examinations every year?

So far, the best way to treat colorectal cancer is early detection, early diagnosis and early treatment. But why do many people undergo physical examinations every year and eventually get colorectal cancer, and the first discovery is often in the middle and late stages?

We all know that the best way to detect early colorectal cancer is colonoscopy. Some people think that B-ultrasound, CT, and blood tumor markers can detect the existence of early colorectal cancer. Obviously, this is unscientific or professional.

We have always Emphasize the importance of early detection, early diagnosis and early treatment. In fact, in addition to colonoscopy, other inspection methods cannot do it. When they can do it, colorectal cancer has spread throughout the body. At this time Even if it is found, the significance is not great, because the patient can only wait to die if the best time for treatment is lost.

At present, although colonoscopy is included in the physical examination items of domestic hospitals, most people refuse it. Because of the many misunderstandings of this type of examination by the public, its penetration rate is far from comparable to that of B-ultrasound, CT or even blood tumor markers. ratio.

Without colonoscopy, colorectal adenomatous polyps and early colorectal cancer cannot be effectively diagnosed. It is conceivable that once they escape monitoring, they tend to undergo malignant transformation or metastasize through lymph and blood circulation within a short period of time.

This is the important reason why you may still get colorectal cancer if you do physical examinations every year.

In fact, what is even more heartbreaking is that 50%-60% of colorectal cancer patients in medicine are often found in the middle and late stages. When symptoms appear in the early stage, the patients do not pay attention to it.

They do not know the importance of colonoscopy and choose other The method of examination may also conceal the existing lesions and mistakenly believe that they are healthy until the symptoms gradually worsen.

At this time, the tumor has often infiltrated the entire intestinal wall and even metastasized. At this time, even if the diagnosis is confirmed, the treatment effect It will not be particularly good.

Therefore, for those at high risk of colorectal cancer, colonoscopy must be added to the physical examination items.

Second, since colonoscopy is so important, who should receive colonoscopy regularly?

①Because colorectal adenomatous polyps and colorectal cancer may have genetic factors, such as typical familial adenomatosis, we recommend that patients with a family history should undergo colonoscopy regularly, 1-2 times a year.

②Some studies have found that the incidence of colorectal cancer increases after appendectomy or cholecystectomy. Therefore, for patients who have already been cholecystectomy, we also recommend regular colonoscopy, which can be performed every 2-3 years.

③Patients with unexplained blood in the stool or persistent fecal occult blood positive should undergo colonoscopy promptly.

④Patients with unexplained weight loss and anemia should receive colonoscopy in time.

⑤Patients with gastrointestinal symptoms, such as diarrhea, constipation, changes in bowel habits, abdominal pain, abdominal distension, etc., should undergo colonoscopy in time; for patients with other benign diseases of the large intestine, such as chronic colitis and inflammatory bowel disease According to the situation, colonoscopy can be performed once every 1-2 years.

⑥ Smoking and alcohol abuse, lack of exercise, low intake of vegetables and fruits, long-term high-fat diet, age over 40 years old, because the incidence of colorectal adenomatous polyps and colorectal cancer is closely related to poor lifestyles, so for these people, intestinal The advantages of endoscopic screening for colorectal diseases outweigh the disadvantages. We recommend colonoscopy once every 3-5 years.

⑦Patients who have clear colorectal polyps, have undergone surgery or have not undergone surgery, and have undergone radical resection of colorectal cancer, these two groups must be closely followed up, and colonoscopy should be performed 1-2 times a year. Never take it lightly, because polyps may transform Colorectal cancer, even if polyps and colorectal cancer have been removed, they are still likely to recur, and the time is often within 5 years.
